Product information

Description

The Noctua NF-A4x20 5V is a compact 40x20 mm cooling fan engineered for efficient, low-noise operation in 5V systems. It incorporates Flow Acceleration Channels and Noctua's AAO frame to improve airflow and static pressure for demanding small-form-factor cooling tasks. The fan uses Smooth Commutation Drive technology and SSO2 bearings to ensure smooth rotation and long-term stability, and comes with modular cabling and the OmniJoin™ Adaptor Set.

Advantages

The NF-A4x20 5V delivers a balance of high rotational speed (up to 5000 RPM) and controlled airflow (9.4 m³/h) tailored for 5V applications, while remaining quiet thanks to aerodynamic optimizations. Durable SSO2 bearings and refined motor control provide low vibration, reliable lifespan and stable performance over time. Included modular cables and adaptor set simplify installation in varied setups.

Suitable for

  • Cooling compact PC cases and small form-factor builds
  • Embedded devices and single-board computers running on 5V
  • Router, NAS or network equipment cooling in tight spaces
  • Custom projects and electronics enclosures requiring a 40 mm fan

Key specifications

  • Dimensions: 40 x 20 x 40 mm
  • Operating voltage: 5V
  • Maximum speed: up to 5000 RPM
  • Airflow: 9.4 m³/h

How to use

Mount the fan in the intended fan slot or enclosure using compatible screws or brackets for 40 mm fans. Connect the fan to a 5V supply or header following the polarity markings on the connector. Use the supplied modular cables and OmniJoin™ adaptors if the target connector differs from the fan’s cable. Ensure clear airflow paths and avoid obstructing the blades for optimal performance.

Usage recommendations

The NF-A4x20 5V is best used where compact dimensions and 5V operation are required; position it to create direct airflow over heat-generating components and keep intake/exhaust paths unobstructed. For prolonged reliability, verify mounting minimizes vibration transfer to the chassis.
